I recently attended a tax webinar and the instructor I believe wasn't too impressed with that Iris system. I agree with Rick and Lisa and I don't plan on using that Iris system. I have been using AMS for years to print out the 1099 forms and having the clients mail them. AMS also offers electronic filing of these forms (and W2S) in partnership with NELCO,  who I believe is the third party administrator. That's what I plan on using and hopefully it works out. If anyone has used AMS/nelco to electronically file these forms in past then please let us know how it worked out. But like Lisa, I will also order the paper forms and envelopes from NELCO just in case there are issues. Hopefully IRS won't charge any penalties if someone has to paper file. It just amazes me that the IRS makes these mandates, and apparently do not consider the difficulties that taxpayers and tax professionals may encounter. You know the taxpayers that pay their salaries.
